When a memblock allocation APIs are called with align = 0, the alignment is
implicitly set to SMP_CACHE_BYTES.
Replace all such uses of memblock APIs with the 'align' parameter explicitly
set to SMP_CACHE_BYTES and stop implicit alignment assignment in the
memblock internal allocation functions.
For the case when memblock APIs are used via helper functions, e.g. like
iommu_arena_new_node() in Alpha, the helper functions were detected with
Coccinelle's help and then manually examined and updated where appropriate.
The direct memblock APIs users were updated using the semantic patch below:
